The primary purpose of the present invention is to provide a timing device of hybrid power that drives a movement of and functions as an auxiliary unit for the timing device. To achieve the purpose, electric power from a power supply is delivered in time to an electro-magnetically driving unit through an automatic control unit manipulated by a mechanical kinetics storage status detection unit to produce mechanical kinetics. Accordingly, a main spring barrel or a potential difference weight of the kinetics storage unit is driven to further drive a wheel chain of the timing device and automatically suspend driving upon the completion of winding the wheel train.
